Insert first opposition observations (most available few weeks/months after discovery)[this step improves the preliminary orbit using differential corrections
to calculate the one-opposition orbit]

Insert all available observations (possibly multi-opposition)[this step improves the one-opposition orbit using differential corrections
to calculate the final orbit]
